A statistical study of the luminosity gap in galaxy groups

open access: yes, 2010
The luminosity gap between the two brightest members of galaxy groups and clusters is thought to offer a strong test for the models of galaxy formation and evolution.

A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

open access: yesWildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Una nueva connotación del riesgo social: La administración como mecanismo tecnocientífico

open access: yesEntramado, 2019
El presente artículo de investigación plantea que la administración se ha constituido en un mecanismo tecnocientífico, generador de riesgo social; se parte de la visión en la que la ciencia y la técnica están plenamente vinculadas en el campo ...

SO(4) Symmetry of the Transfer Matrix for the One-Dimensional Hubbard Model

open access: yes, 1997
The SO(4) invariance of the transfer matrix for the one-dimensional Hubbard model is clarified from the QISM (quantum inverse scattering method) point of view. We demonstrate the SO(4) symmetry by means of the fermionic R-matrix, which satisfy the graded

Relationships Between European Wildcats and Domestic Cats in an Area of Sympatry: Exploring Key Conservation Questions on Hybridization and Disease Transmission

open access: yesAnimal Conservation, EarlyView.
We have found evidence of behavioural barriers for both hybridization and disease transmission between European wildcats and domestic cats. This includes hierarchical interspecies exclusion enforced by wildcats, as well as sexual selection exerted by wildcat females.

Solutions to the relativistic precession model [PDF]

open access: yes, 2014
The relativistic precession model (RPM) can be used to obtain a precise measurement of the mass and spin of a black hole when the appropriate set of quasi periodic oscillations is detected in the power-density spectrum of an accreting black hole. However,

THE GLOBULAR CLUSTER NGC 6402 (M14). I. A NEW BV COLOR–MAGNITUDE DIAGRAM [PDF]

open access: yes, 2013
We present BV photometry of the Galactic globular cluster NGC 6402 (M14), based on 65 V frames and 67 B frames, reaching two magnitudes below the turnoff level.

Nonresponse Bias in Household Inflation Expectations Surveys

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract This paper uses microdata from the Reserve Bank of New Zealand's Household Inflation Expectations survey to evaluate the effects of nonresponses to the inflation expectations question in the survey. We find nonresponses lead to substantial underrepresentation of some demographic groups in the survey: young, female, low‐income, and minority ...

Processing, microstructure and mechanical properties of bimodal size SiCp reinforced AZ31B magnesium matrix composites

open access: yesJournal of Magnesium and Alloys, 2015
The bimodal size SiC particulates (SiCp) reinforced magnesium matrix composites with different ratios of micron SiCp and nano SiCp (M-SiCp:N-SiCp = 14.5:0.5, 14:1, and 13.5:1.5) were prepared by semisolid stirring assisted ultrasonic vibration method ...
